Customer Reviews

This flashlight has a very solid build and nice weight.
Ken W
We live in a semi-rural area and having a good flashlight to light the way and illuminate any wayward critters while walking the dogs at night is very important.
Rebecca
It is easily and quickly accessible and casts a beam of full daylight brightness over 100 yards easily.

I bought this flashlight after realizing that there are flashlights way better than my old 4D mag light. This thing is a beast, I am sure you can buy other lights that have more lumens and what not, but this thing uses AA's, no need to worry about Li-ion and the troubles/cost that comes with those.

This light has impressed every single person that has seen it. Everyone thought I was crazy when I told them I bought a $130 flashlight that is until they saw what it could do.

I had the light long enough that I decided to get 16 of the amazon basic NiMH 2000mAh and a BC-700 Lacross Charger which has made for a great set up.

Pros-
Quality of machining
Brightest AA flashlight ever
Hidden SOS and Strob modes

Cons-
Has a greenish tint (only discernible indoors)
The mode switch on the side is not very sensitive, (it takes a deliberate and often repeated effort to change modes)

Over all great!

This is what I like about this light:
- "2 D" size, fits my hand nicely.
- Uses standard batteries that I can find anywhere.
- Separate buttons for on/off and mode changes. I can not put into family friendly words now much I hate, truly HATE flashlights with a single on/off/mode button, especially if they have a ton of level and flashing modes. I don't want a flashlight to have an " user interface" I need to learn. Come on, it's a flashlight! Anyway, the implementation here is good. Hit one button to turn it on and off, another button to cycle the modes.
- Fit and finish is superb.

Other observations:

Yes, the color isn't perfect. Mine is purplish in the spill regions and a little greenish in the center at the brightest setting. The low settings are a little purple/blue. It's a total non issue in real world usage as far as I'm concerned.

The low setting is perfect for around the house and confined spaces. The highest setting lights up whatever you point it at like the sun.

As of the date of this review, the U2 version isn't any more expensive than the previous version. Just look around. I wouldn't pay extra for U2.

Update 1/24/13: One important thing I forgot to mention is that this flashlight does not appear to use a PWM to achieve different light levels. What that means is that it doesn't flash the LED for different lengths of time or, if it does, it's at such a high frequency that you can't see it. If they did use that technique to change the output it would be incredibly annoying in a light like this because you'll be using the lower power modes often.

If you need a solid, dependable, blinding white light...this is the one! Perfect for emergency preparedness, home security, search and recue, law enforcement/security work or camping. A MUST HAVE for your bug out bag. Not as heavy or cumbersome (but just as solid) as a MagLight or Streamlight. This light ignites with sunlike brilliance and will pierce the blackest stormiest night. This is the light you NEED by your bedside and in each vehicle. You can read the specs but seeing is believing. I've tested it in the neighborhood and in the thick New England forests for the past few nights and the neighbors peer out and phones start ringing. Local police even cruised by and wanted to know what we're SEARCHING for! They now own a FENIX for their own. If you are serious about emergency preparedness, this is the light you need. Worth EVERY penny. I suggest a 16 pack of Sanyo Enneloop "AA" NiMH rechargeble batteries with charger and a backup pack of premium alkaline batteries. Just remember to unscrew the tail cap 3 or 4 turns when you store it. I now own 2 of these and have the TK70 on order. With Fenix flashlights and a couple of Coleman Northstar Dual Fuel Lanterns, you're ready for the dark days ahead. Remember, there are only three kinds of men: wolves, sheep and sheepdogs. Which one are you?

This flashlight has a very solid build and nice weight. Fits my hand perfectly, excellent non-slip grip styling in metal casing.

I read many flashlight reviews and researched this light extremely well, before placing my hard earned money on this purchase.
There is no way to take a photo that demonstrates the power of this light. The bulb and reflector are constructed of high grade materials.

When I turn on the turbo mode - it is just incredible. When holding the flashlight in one hand and shining it on the other hand - approx a foot and a half away - I can feel heat!

I have never felt heat from a LED flashlight - from the light itself. It's awesome how well this flashlight is engineered to deliver as promised.

I also ordered rechargeable Sanyo Batteries Powered by eneloop, 2500mAh typical / 2400 mAh minimum High Capacity. Thankful, I did that!

I recieved the flashlight a couple days before I got the Sanyo Batteries. When I tested the light with my own batteries, it would not stay in turbo mode for very long. But after getting the Sanyo 2500mAh batteries - I am all good to go.
I have not tested the light in turbo to see how long it will work with the Sanyo batteries. I simply know - that it now has the power I need when I want it.

Having this flashlight is like having a car or truck with a V8 engine. You don't have to floor it and make it run in turbo all the time, but it sure is nice to know it is there when/if you need it.

You will love this flashlight. I expect it to take care of all my flashlight needs for the rest of my life.
